目前的有源矩阵有机发光二极体(Active-matrix organic light-emitting diode,AMOLED)屏幕在手机的运用越来越广泛,对比传统液晶显示器(Liquid Crystal Display,LCD),AMOLED屏幕非常薄,并且可以在屏幕中集成触摸层,所以在做超薄机方面,它更有优势。AMOLED自发光,单个像素在显示黑色时下不工作,显示深色时低功耗。所以AMOLED在深色下省电,并且具有传统LCD几百倍。AMOLED具有一定的柔韧性,比玻璃基板的LCD屏幕不易损坏。因此AMOLED的供电也有别于薄膜场效应晶体管LCD(Thin Film Transistor,TFTLCD),OLED需要在正负极上施加一定电压才能发光,AMOLED的正负电压需要用特殊的DCDC来供电。目前AMOLED采用的驱动电路,一般采用PMIC供电。PMIC将传统的多路输出电源封装在一颗芯片内,使得多电源应用场景高效率更高。一般具有多个直流至直流变换器(DC-DC converter)和多个低压差线性稳压器(Low dropout voltage,LDO)。The current active matrix organic light-emitting diode (Active-matrix organic light-emitting diode, AMOLED) screen is more and more widely used in mobile phones, compared with traditional liquid crystal display (Liquid Crystal Display, LCD), AMOLED screen is very thin, and The touch layer can be integrated in the screen, so it has more advantages in making ultra-thin machines. AMOLED is self-luminous, a single pixel does not work when displaying black, and low power consumption when displaying dark color. So AMOLED saves power in dark color, and has hundreds of times of traditional LCD. AMOLED has a certain flexibility and is less damaged than LCD screens with glass substrates. Therefore, the power supply of AMOLED is also different from thin film field effect transistor LCD (Thin Film Transistor, TFTLCD). At present, the driving circuit used by AMOLED generally adopts PMIC power supply. The PMIC encapsulates the traditional multi-output power supply in one chip, which makes the multi-power supply application scenario more efficient and efficient. Generally, there are multiple DC-DC converters (DC-DC converters) and multiple low dropout linear regulators (Low dropout voltage, LDO).
目前,终端上的AMOLED的驱动电路的使用和布局还是有待提高,主要存在如下缺陷:1)使用集成PMIC,成本高。2)集成PMIC精度相比单独LDO驱动,精度低。3)PMIC布局空间大。4)PMIC功耗大。5)PMIC可靠性低。6)目前的PMIC兼容性非常不好。At present, the use and layout of the driving circuit of the AMOLED on the terminal still needs to be improved, and there are mainly the following defects: 1) The use of an integrated PMIC is costly. 2) The precision of the integrated PMIC is lower than that of the single LDO driver. 3) PMIC layout space is large. 4) PMIC power consumption is large. 5) PMIC reliability is low. 6) The current PMIC compatibility is very poor.
因此,为了克服上述缺陷,本申请实施例提供了一种电源装置、电子设备及供电方法,能够精简用于为AMOLED供电的电源驱动,从而减少成本。Therefore, in order to overcome the above-mentioned defects, the embodiments of the present application provide a power supply device, an electronic device, and a power supply method, which can simplify the power supply driving for powering the AMOLED, thereby reducing the cost.
